Hello Leandro,

If you are under Proxmox 6.4, you cannot move "accidentaly", by software 
upgrades, to 7.0. Because 6.x is based on Debian 10, and 7.x on Debian 
11, so you have to change the repository to point to the newer release.

What I do personnaly is to test the upgrade on a test cluster, to see 
how it works. I have an old server on which I setup a nested proxmox ve 
cluster with three small VMs. I test the upgrade process on this nested 
cluster, before applying it to production cluster.

For your produxtion cluster, you should have backups of your VMs (for 
example on an NFS storage). It would be indeed a good thing to have à 
third host to have a minimum cluster with quorum.

Good luck !
